The first synthesis of a newly found naturally occurring anti-malarial nonenolide is described. A pivotal step in the synthesis is the ring-closing metathesis of a dienoic ester prepared by coupling an acid and alcohol that were stereoselectively synthesized from (S)-α-hydroxy-γ-butyrolactone and 1,2-O-isopropylidene d-glyceraldehyde, respectively.
描述了新发现的天然存在的抗疟壬烯醚化物的第一合成。合成中的关键步骤是二烯酸酯的闭环复分解反应,该二烯酸酯是通过偶联由(S)-α-羟基-γ-丁内酯和1,2 - O-异亚丙基d-甘油醛立体选择性合成的酸和醇制得的, 分别。
